Definitions

  • the present invention relates to a display device, in particular for a motor vehicle.
  • Head-up display (HUD) devices are known, in particular with the projection of an image onto a windscreen as described in the document U.S. Pat. No. 5,214,413 or in the document WO 2007/090824 A1. It is advantageous if the projected image, of the head-up display device, can be adapted in a way that is flexible to the various needs of users, in particular drivers of motor vehicles.
  • a drawback of such devices of the known art consists in the fact that an optical path that makes an image generated by a projection module visible to a user of the display device is generally poorly variable or even non-variable.
  • the present invention has in particular the object of palliating the drawbacks of the known art, in particular those mentioned above, and also has the object of proposing a display device that is capable of being adapted to various needs of various users of a motor vehicle.
  • a display device in particular for a motor vehicle, comprising
  • the optical path comprising at least one reflection element
  • the reflection element being designed to reflect at least partially an image originating from the projection module in a normal direction of gaze of a user of the display device
  • the image originating from the projection module being generated by the projection module
  • the display device being designed to be operated in a first mode of operation and in a second mode of operation
  • a preferred refinement of the invention resides in the fact that in the second mode of operation of the display device, only a part of the image generated by the projection module is visible to the user of the display device.
  • the optical path can be provided, in the first mode of operation of the display device as well as in the second mode of operation of the display device, that the same size of field of view is produced for a driver.
  • the only difference is that, instead of, for example, representing for the user the complete image generated by a projection module, only a part of this image is transmitted by the optical path in the field of view of the user of the display device.
  • a particularly preferred refinement of the invention resides in the fact that in the second mode of operation of the display device, the whole image generated by the projection module is visible to the user of the display device.
  • a particularly preferred refinement of the invention resides in the fact that the display device comprises a human-machine interface or that the display device is associated with a human-machine interface, and that via the human-machine interface, following an interaction of the user of the display device, an item of selection information is transmitted to the display device such that the display device is operated, either following the first mode of operation, or following the second mode of operation, depending on the item of selection information.
  • Yet another particularly preferred refinement of the invention resides in the fact that the item of information is generated following identification of the user of the display device.
  • a particularly preferred refinement of the invention resides in the fact that the display device comprises a liquid crystal display (LCD) module.
  • LCD liquid crystal display
  • the display device comprises a matrix display module.
  • a particularly preferred refinement of the invention resides in the fact that the reflection element is an element positioned at a distance with respect to a windscreen of the motor vehicle.
  • reflection element is designed to be retractable between, on the one hand, a use position of the reflection element, and, on the other hand, a rest position of the reflection element.
  • FIG. 1 is a schematic representation of a display device according to the present invention
  • FIG. 2 is a schematic representation of the field of view of a user of the display device according to the present invention with the image projected from the projection module, and
  • FIG. 3 is a schematic view of a cross-section of a display device according to the present invention.
  • a display device 10 comprises a projection module 11 that generates an image in the normal direction of gaze 15 of a user of the display device 10 along an optical path 12 .

  • the optical path 12 can comprise a (single) reflection element, as represented in FIG. 3 .
  • the optical path 12 can also comprise two reflection elements (not represented).
  • the display device 10 can also comprise—in another variant not represented in the figures—more than two reflection elements 13 .
  • the reflection element 13 can be part of the windscreen 14 of the vehicle. In another preferred variant of the invention, the reflection element 13 is an element positioned relatively close to the windscreen 14 , as is represented in FIG. 3 . In another preferred variant of the invention (not represented in the figures), the reflection element 13 is an element positioned at a distinct distance with respect to the windscreen 14 .
  • the reflection element 13 can be designed to be retractable to between, on the one hand, a use position of the reflection element 13 , and, on the other hand, a rest position of the reflection element 13 .
  • the normal direction of gaze 15 is the direction of gaze of a user of the display device 10 , in particular a vehicle driver, when the latter views, in particular through the windscreen 14 , the outside of the motor vehicle which lies for example in front of the vehicle.
  • the display device 10 comprises, preferably in the projection module 11 , a display module being a Liquid Crystal Display (LCD) module.
  • the display module can also be a matrix display module. It is also possible, according to the present invention, to combine a liquid crystal display (LCD) module with a matrix display module, i.e. to use a combined display module comprising a part of the liquid crystal display module and a part of the matrix display module.
  • a passive matrix display module in the case of a matrix display module.
  • the display device 10 is designed to be operated in a first mode of operation and in a second mode of operation, the first mode of operation of the display device 10 corresponding to a first configuration of the optical path 12 , and the second mode of operation of the display device corresponding to a second configuration of the optical path 12 .
  • the optical path 12 comprises at least one variable element that effects the first and second configuration of the optical path.
